1.        Artificial intelligence emerged during the late 1950’s as an academic discipline based on the assumption that computers are able to be programmed to think like people.

(A) are able to be programmed to think like people

(B) were able to be programmed to think as people

(C) can be programmed to think as people can

(D) could be programmed to think like people（D）

(E) are capable of being programmed to think like people do

                这是大全注释上的解释  

                  119, sec18-06

                  A, are able to be done必错.

                  B, 同上，computers as people意思错。

                  C, as people can (be programmed)意思错。

                 D, correct. to think like people向人一样思考, 可以。

                 E, are capable of being programmed错, capable of doing不用被动; like people do错。

    看了以后还是不太明白， 1are able to be done为什么一定错？ 2这里为什么不可用as people?

    求解答，谢谢

be able to do表明有能力做某事,是没有被动的~
as解释为同...一样时,是做连词,后面要加句子,不能只加n.
